Broken
Arrived extremely broken. Literally not one piece was large enough to make any arch or design. Had to glue everything together and eventually just gave up.

No cracks!
Took a chance on ordering despite the reviews about the rocks breaking. Mine came well packaged and nothing cracked. Very nice shapes. I’m still messing with the rock placement in my tank. Im happy overall.

Very sensitive; great hardscape
One of the arches was broken, but I was able to use some of the broken bits to create further arches. Just be careful handling them. I create this hard scape in a 32 bio cube, lots of negative space and all of the arches have holes drilled into them, 3 of them which some of the smaller fish will probably swim through, a great way to build vertical height without turning your tank into a pile of rocks. They are much bigger than you think
